HEL ASAP! A student listed the characteristics of chemical and nuclear reactions. Chemical and Nuclear Reactions X Y Changes the identity of the element Does not change the identity of the element Which of these statements best explains the identity of Reaction X? (5 points) It is a nuclear reaction because the identity of elements changes when there is a change in the number of protons and neutrons.

It is a chemical reaction because the identity of elements change when there is a change in the mass of the atoms involved.

It is a chemical reaction because the identity of elements change when there is a change in the overall energy of the system.

It is a nuclear reaction because the identity of elements change when there is a change in the number of outermost electrons.

It is a nuclear reaction because the identity of elements changes when there is a change in the number of protons and neutrons.

Explanation:

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
